Description

本発明は、電圧検出端子を備えたバスバーモジュール及び該バスバーモジュールを有して構成される電源装置に関する。   The present invention relates to a bus bar module having a voltage detection terminal and a power supply device configured to include the bus bar module.
従来、電圧検出端子を備えたバスバーモジュールとして、電圧検出端子が隣接するバッテリ同士の間に設けられたバレル部を介して電線配索部に接続されるものが提案されている(例えば、特許文献1参照)。特許文献1に記載されたバスバーモジュールでは、バレル部がバッテリ同士の間に設けられていることで、電圧検出端子と他の部品との干渉が防がれている。   Conventionally, as a bus bar module provided with a voltage detection terminal, one in which the voltage detection terminal is connected to an electric wire routing portion via a barrel portion provided between adjacent batteries has been proposed (for example, Patent Documents). 1). In the bus bar module described in Patent Literature 1, interference between the voltage detection terminal and other components is prevented by providing the barrel portion between the batteries.
特開2013−33707号公報JP 2013-33707 A
しかしながら、特許文献1に記載のバスバーモジュールでは、図5に示すように、電圧検出端子101はバッテリの電極と電気的に接続される端子部102とバレル部103とを有し、端子部102とバレル部103とはバスバーによるバッテリの接続方向に並設されているため、電圧検出端子101をバスバー収容部104に収容するために、端子部102に力を加えて電圧検出端子101全体をバスバー収容部104と電線配索部105との対向方向に撓ませようとした際に、端子部102とバレル部103との境界部106付近が接続方向にも撓んでしまい、電圧検出端子101をバスバー収容部104に収容しづらくなり、バスバーモジュール100は組立性に劣るという不都合があった。また、境界部106付近の接続方向への撓みを解消するためにバレル部103を対向方向に長く形成する構成も考えられるが、このような構成においてはバスバーモジュール全体の寸法が大きくなってしまうという不都合が考えられる。   However, in the bus bar module described in Patent Document 1, as shown in FIG. 5, the voltage detection terminal 101 includes a terminal portion 102 and a barrel portion 103 that are electrically connected to the electrode of the battery. Since the barrel portion 103 is juxtaposed in the battery connection direction by the bus bar, the entire voltage detection terminal 101 is accommodated in the bus bar by applying a force to the terminal portion 102 in order to accommodate the voltage detection terminal 101 in the bus bar accommodation portion 104. When an attempt is made to bend in the direction in which the portion 104 and the wire routing portion 105 face each other, the vicinity of the boundary portion 106 between the terminal portion 102 and the barrel portion 103 is also bent in the connection direction, and the voltage detection terminal 101 is accommodated in the bus bar. Therefore, the bus bar module 100 is inferior in assemblability. In addition, a configuration in which the barrel portion 103 is formed long in the opposite direction in order to eliminate bending in the connection direction in the vicinity of the boundary portion 106 can be considered, but in such a configuration, the overall size of the bus bar module is increased. An inconvenience is considered.
本発明の目的は、全体を小型化するとともに組立性を向上させることができるバスバーモジュール及び電源装置を提供することにある。   The objective of this invention is providing the bus-bar module and power supply device which can improve assembly property while reducing the whole size.
本発明のバスバーモジュールは、複数のバッテリのうちの隣接するバッテリの電極同士を接続するバスバーと、前記バスバーを収容するとともに該バスバーの接続方向に配列された複数のバスバー収容部を有するケース体と、前記バスバー収容部に収容されるとともに接続された前記電極を検圧するための電圧検出端子と、を備えたバスバーモジュールであって、前記ケース体は、前記バスバー収容部から前記接続方向と交差する方向に離隔するとともに前記接続方向に沿って延びる電線配索部と、前記隣接するバッテリ同士の間において前記バスバー収容部と前記電線配索部とを連通するとともに前記電圧検出端子に接続される電圧検出線を収容する電線収容部と、を備え、前記電圧検出端子は、前記バスバー収容部において前記隣接するバッテリのうち一方に対応して収容される端子部と、前記電圧検出線に接続されるバレル部と、前記バスバー収容部と前記電線配索部との対向方向における前記端子部の前記電線収容部と反対側の端部と前記バレル部とを接続する連結部と、を有して構成され、前記バレル部と前記連結部とは、前記対向方向及び前記接続方向に傾斜して設けられていることを特徴とする。 A bus bar module according to the present invention includes a bus bar that connects electrodes of adjacent batteries among a plurality of batteries, and a case body that houses the bus bar and has a plurality of bus bar housing portions arranged in the connecting direction of the bus bar.

It is characterized by that.
以上のような本発明によれば、隣接するバッテリ同士の間に設けられた電線収容部にバレル部が配されていることで、バレル部の長さを確保しつつバスバー収容部と電線配索部との間の寸法を小さくすることができ、バスバーモジュール全体を小型化することができる。さらに、端子部の対向方向における電線収容部と反対側の端部と連結部とが接続されることで、バレル部及び連結部の対向方向寸法を確保することができ、電圧検出端子をバスバー収容部に収容するために対向方向に撓ませることが容易となり、電圧検出端子全体が接続方向に撓むことが防がれ、組立性を向上させることができる。   According to the present invention as described above, the barrel portion is arranged in the electric wire accommodating portion provided between the adjacent batteries, so that the length of the barrel portion is secured and the bus bar accommodating portion and the electric wire are arranged.

Furthermore, by connecting the end portion on the opposite side to the wire housing portion in the facing direction of the terminal portion and the connecting portion, the dimensions in the facing direction of the barrel portion and the connecting portion can be secured, and the voltage detection terminal is accommodated in the bus bar. Therefore, it is easy to bend in the opposite direction to be accommodated in the portion, the entire voltage detection terminal is prevented from being bent in the connection direction, and assemblability can be improved.
また、バレル部と連結部とが傾斜して延びていることで、連結部が接続方向に延びる構成と比較して、連結部とバレル部との合計の接続方向寸法を小さくすることができ、バスバーモジュール全体の接続方向寸法を小さくすることができる。 In addition , since the barrel portion and the connecting portion extend in an inclined manner, the total connecting direction dimension of the connecting portion and the barrel portion can be reduced as compared with the configuration in which the connecting portion extends in the connecting direction. The connection direction dimension of the entire bus bar module can be reduced.
さらに、本発明のバスバーモジュールでは、前記連結部は、前記端子部における前記接続方向の端部に接続され、前記電圧検出端子は、前記端子部における前記対向方向の少なくとも一方側の端部に設けられるとともに該電圧検出端子を前記バスバー収容部に固定するための係止片を有して形成され、前記バスバー収容部には、前記係止片を係止する係止受け部が設けられていることが好ましい。このような構成によれば、端子部が接続方向の端部において連結部に接続されるとともに、対向方向の端部に係止部が設けられることで、連結部と係止部との干渉を防ぎつつ電圧検出端子をバスバー収容部に固定することができる。   Furthermore, in the bus bar module of the present invention, the connecting portion is connected to an end portion of the terminal portion in the connection direction, and the voltage detection terminal is provided at an end portion of at least one side of the terminal portion in the facing direction. And is formed with a locking piece for fixing the voltage detection terminal to the bus bar housing portion, and the bus bar housing portion is provided with a locking receiving portion for locking the locking piece.

That is, since the barrel portion 331 is connected to the Y direction outer side end portion of the terminal portion 332 via the connecting portion 333, the Y direction dimension of the barrel portion 331 and the connecting portion 333 can be increased, and the voltage detection terminal When trying to bend the whole 33 in the Y direction, it is prevented from being bent in the X direction, and the assemblability when accommodated in the bus bar accommodating portion 321 can be improved.
さらに、検圧線収容溝323が第一収容部321Aと第二収容部321Bとの間に配されていることで、バレル部331のY方向寸法を確保しつつバスバー収容部321と電線配索部322との間のY方向寸法を小さくすることができ、バスバーモジュール3全体のY方向寸法を小さくするとともに電源装置1全体のY方向寸法を小さくして小型化することができる。   Furthermore, the pressure-line housing groove 323 is disposed between the first housing portion 321A and the second housing portion 321B, so that the bus bar housing portion 321 and the electric wire are routed while ensuring the dimension in the Y direction of the barrel portion 331. The dimension in the Y direction with respect to the portion 322 can be reduced, the overall Y direction dimension of the bus bar module 3 can be reduced, and the overall Y direction dimension of the power supply device 1 can be reduced to reduce the size.
また、バレル部331と連結部333が略同一の方向に延びていることで、構成を簡単化することができる。また、バレル部331と連結部333とがY方向及びX方向に傾斜して延びていることで、バレル部331と連結部333との合計の長さ寸法を確保しつつ検圧線収容溝323のX方向寸法を小さくすることができ、バッテリ21同士の間隔を狭くして電源装置1のX方向寸法を小さくして小型化することができる。   Moreover, since the barrel part 331 and the connection part 333 are extended in the substantially the same direction, a structure can be simplified. In addition, since the barrel portion 331 and the connecting portion 333 extend while being inclined in the Y direction and the X direction, the pressure detection line receiving groove 323 is secured while ensuring the total length of the barrel portion 331 and the connecting portion 333. The X-direction dimension of the power supply device 1 can be reduced by reducing the distance between the batteries 21 and reducing the X-direction dimension of the power supply device 1.
また、端子部332がX方向端部において連結部333に接続されるとともに、Y方向端部において係止片332bと係止受け部321bと突出片321aとによってバスバー収容部321に固定されていることで、連結部333と係止片332b及び突出片321aとの干渉を防いでスペースを効率的に利用することができる。   Further, the terminal portion 332 is connected to the connecting portion 333 at the end portion in the X direction, and is fixed to the bus bar housing portion 321 by the locking piece 332b, the locking receiving portion 321b, and the protruding piece 321a at the Y direction end portion. Thus, interference between the connecting portion 333, the locking piece 332b, and the protruding piece 321a can be prevented and the space can be used efficiently.
また、バスバー収容部321と電線配索部322との間にカバー部を係止するための係止溝324が形成されていることで、バレル部331のY方向寸法を確保するために検圧線収容溝323のY方向寸法を大きくしても、ケース体32と電線配索部322の間のスペースを有効に利用することができる。   In addition, since a locking groove 324 for locking the cover portion is formed between the bus bar housing portion 321 and the electric wire routing portion 322, the pressure detection is performed in order to ensure the Y direction dimension of the barrel portion 331. Even if the dimension in the Y direction of the wire housing groove 323 is increased, the space between the case body 32 and the wire routing portion 322 can be used effectively.
